Abstract: The present invention involves a gear assembly of a fuel pump for improved supply of fuel to an automotive engine from a fuel tank. The assembly includes an inner gear and an outer gear matingly cooperating with the inner gear for rotation about an axis. The assembly further includes a pump cover including a cover surface adjacent the inner and outer gears and a pump body including a body surface adjacent the inner and outer gears opposite the pump cover. The cover surface has a primary inlet porting and a secondary outlet porting formed thereon and separated between seal areas. The body surface of the pump body includes a primary outlet porting and a secondary inlet porting separated between seal areas. In use, the inlet portings and the outlet portings of the pump body and the pump cover cooperate together, respectively, such that fuel entering through the inlet portings pass therethrough at a rate at which the gear assembly moves. Also, the outlet portings of the pump body and the pump cover cooperate together to allow fuel to pass therethrough at the rate at which the gear assembly moves.

Abstract: A fuel volume accumulator is provided to hold rail pressure for hot engine restart and then reduce fuel pressure when the engine is off thereby minimizing evaporative emissions during diurnal cycles by preventing pressure build up as a temperature of a fuel system rises. The fuel volume accumulator comprises a fuel inlet body, and a moving element adapted to communicate with an inner surface of the fuel inlet body to define a fuel chamber. The fuel chamber is adapted to expand with substantially minimal pressure resistance until the extent of its volume is encountered. The fuel inlet body is in open communication at a first end with a fuel pump via a check valve and a fuel rail via an orifice which restricts fuel flow to substantially maintain a quick fuel rail re-pressurization.

Abstract: A regenerative pump for an automotive fuel pump assembly comprises a cover and body that define a chamber and a ring impeller disposed within the chamber. An inlet is formed in the cover, and a discharge port is formed in the body. The body includes a pumping channel adjacent the chamber and having a discharge end section extending from the discharge port. The port diameter is greater than the radial width of the discharge end section. Also, the discharge end section has a depth that progressively increases adjacent the discharge port. The configuration of the discharge port and the channel end section reduces frictional and turbulent losses and thereby improves pumping efficiency.
